Sit back easily to cause cervical spondylosis: the ancients said, sit back and relax. However, there are many patients with stiff neck in clinical medicine because they slept too high a pillow. If you sleep on a pillow that is too high, it will change the normal physiological curvature of the cervical spine, causing muscle fatigue damage and ligament stretch strain, resulting in cramps, inflammation, etc., and symptoms such as neck and shoulder pain, hand numbness, dizziness and other symptoms. Clinically, high pillows are one of the common causes of stiff neck and cervical spondylosis. Low pillows make blood supply unbalanced: high pillows are not good, is it good to use low pillows or not use pillows at all? Experts believe that low pillows or no pillows are also bad for health. Some people think that they can recover without a pillow after suffering from cervical spondylosis. In fact, this idea is unscientific. Without pillows, people tend to lean back too much when lying on their backs, and they are easy to open their mouths to breathe, which can lead to dry mouth, dry tongue, sore throat and snoring. If you lie on your side without pillows, one side of the neck muscles will also cause cramps and pain due to excessive stretching and fatigue, resulting in "stiff neck".
A pillow that is too low will also make the blood supply unbalanced and easily cause congestion and swelling of the nasal mucosa. The nasal mucosa is very sensitive, and the swelling will affect breathing. If the neck and shoulders are sore after waking up, it may also be caused by the pillow being too low or not using it.
So, how high should the pillow be? An ancient Chinese medical book once pointed out: "The size of the height makes the side lying just at the shoulder level, that is, supine also feels comfortable." In other words, the height of the pillow is based on supine. It is advisable to keep the head and torso level, that is, one punch with the pillow high when lying on the back, and one and a half punches with the pillow high when lying on the side. Generally speaking, a pillow height of 10-15 cm is more appropriate, and the specific size depends on each person's physiological curvature.
In addition to the height of the pillow, experts believe that the hardness of the pillow should also be paid attention to. A very hard pillow has a small contact area with the head, increases the pressure, and makes the scalp uncomfortable. On the contrary, the pillow is too soft to maintain a certain height, the neck muscles are prone to fatigue, and it is not conducive to sleep, and the head sinks during it, which affects blood circulation. Therefore, the pillow should be slightly softer without losing a certain degree of hardness.
Pillows should also have a certain degree of elasticity. If the pillows are too elastic, the head will continue to be subjected to additional elasticity, causing muscle fatigue and injury.
